Today Napeague, tomorrow the world, or at least the East End. That is apparently the mantra of the cousins and entrepreneurs Mark Goldberg and Paul Wayne. The team behind Goldberg’s Famous Bagels, Flagels, and Deli has signed a 10-year lease to open another store, this one on the Napeague stretch in Amagansett, at what is now Espo’s Surf Shop. The new tenants will take occupancy on Feb. 1.
